Make sure notifications are enabled for FirstMove in Settings, and that the app hasn't been force-quit. FirstMove needs to run in the background to deliver alarms reliably. If the problem persists, use the "Send Diagnostics" button on the Profile tab — it generates a report that helps us investigate.
Open the Settings app on your iPhone → tap your name at the top → Subscriptions → FirstMove Chess → Cancel. Apple handles all billing — we don't have access to your subscription directly.
Your rating adjusts after every puzzle using an Elo system. Wrong moves and skips lower it; clean solves raise it. Hints forfeit the rating gain but never cost points. The system is intentionally strict — your rating reflects real performance.
